Write the equation of the line in slope intercept form of the line is perpendicular to
y = 1/2x + 4 and has the
x-intercept 5.

x-2y= -8

Explanation:
Move expression to the left side and change its sign.
y=1/2x+4
To:
y-1/2x=4
Multiply both sides by 2.
2y-x=8
Use the commutative property to reorder the terms.
-x+2y=8
Change the signs on both sides of the equation.
Solution:
x-2y= -8
Hope this helped :)
